How to
1). Use RGN_Tool to extract and save your original boot.bin
- open original 1455CHN .gcd file lastest version and save boot.bin (You will get boot.bin = 482 KB (493,768 bytes) )
2). Use RGN_Tool to extract and save SgMy fw_all and resource
-open original 1460SgMy .gcd file lastest version and save fw_all.bin (You will get fw_all.bin = 11.7 MB (12,336,128 bytes) )
-and save fw1_resources.bin (You will get fw1_resources.bin = 20.4 MB (21,428,996 bytes) )
3). Use RGN_Tool
- Load boot.bin from 1).
- Load fw1_resources.bin from 2).
- Load fw_all.bin from 2
- override hwid to the same as boot (1182)
- save as out.rgn(32.6 MB (34,258,982 bytes)) or save as gupdate.gcd (32.6 MB (34,265,202 bytes))
4). Now you have alternative firmware ., use RGN_Tool to check them. (must have no error.)

5). Flash 1455 with .rgn file via pre-boot mode+Updater.exe

I don't have 1455CHN but I think this should work.
Please rename these folders :: Text-->Textx / Voice --> Voicex / Keyboards --> Keyboardsx before flashing
Rename it back after your 1455 boot up normally.

Good luck.

Note ::
SgMy firmware can displays CHN/TWN JCV.
Avoid to use non-original boot.bin for 1xxx series or you may get dead end.
